[0022] Compared with the prior art, this utility model provides a portable mobile gas analyzer with the following advantages:

[0023] 1. In this portable mobile gas analyzer, when using it, pressing the power button on the main unit turns it on. After powering on, the analyzer automatically enters the main display area, which displays the current date and time, temperature, humidity, and various instrument status information. The main display area displays the gas component names, instantaneous concentration values, and real-time concentration curves. During the measurement process, the gas change trend can be viewed in real time, and the instantaneous gas concentration value can be read. The main display area allows for functions such as starting the gas pump and recording data. When sampling begins on-site, clicking the "Start" button on the main display area starts the gas pump. The gas pump draws gas from the atmosphere, which is then analyzed by the gas sensor to obtain the gas concentration value. Clicking the "Record Data" button starts data recording, the timer starts, and the instrument begins recording data until "Record Data" is clicked again. The instrument automatically calculates and saves the average data. Through the settings of the portable mobile gas analyzer, it is not only convenient to move and meet the needs of on-site emergency testing and outdoor testing, but it can also effectively filter impurities such as oil, water vapor, and dust in the sample gas, improving system stability.

[0024] 2. In this portable mobile gas analyzer, when using it, first place the portable mobile gas analyzer on the ground in the field via the shock-absorbing column. When starting sampling on site, click the "Start" button in the main display area to start the main air pump. The main air pump draws in gas from the atmosphere, and then analyzes the gas through the gas sensor. When the portable mobile gas analyzer is working, it will vibrate. At this time, the slider moves up and down in the slide groove, causing the shock-absorbing column to move up and down. At the same time, the spring of the shock-absorbing column will be compressed or stretched, causing deformation. During this process, the spring will generate an elastic force opposite to the external force, attempting to restore its original shape, thereby offsetting part of the external force and reducing the impact of the impact on the equipment. Since the shock-absorbing column is equipped with rubber plates and steel plates inside, it will further reduce the impact force. Through the combined use of the shock-absorbing column, rubber plates, steel plates, slider, slide groove and spring, the portable mobile gas analyzer can play a buffering and shock-absorbing role, thereby extending the service life of the portable mobile gas analyzer.
